RELATED CASES

The present application is a divisional of, and claims benefit from, U.S. application Ser. No. 13/617,066, filed Sep. 14, 2012, entitled USER INTERFACE WITH CONFIGURATION, REGISTRATION, AND RUNTIME SELECTION OF VIEWS, the contents of which are incorporated herein by reference in their entirety.

BACKGROUND

The present disclosure relates to user interfaces, and more specifically, to configurable user interfaces.

Graphical user interfaces (GUIs) can be created using a variety of different techniques. However, ultimately the goal of the user interface is to define how a user will see data and be able to interact with that data. Although a developer can create source code in a programming language (e.g., Java, C#, etc.) to implement a GUI, toolkits of reusable widgets have been developed that simplify creation of GUIs. For example, a drag-and-drop development environment may be provided that allows a developer to select from a variety of pre-defined widgets and place them onto a pallet so as to create a basic GUI for a particular software application. The developer can then associate various portions of programming code with components of the widgets that will be invoked when a user eventually interacts with the elements of the GUI so as to perform the functionality of the software application.

The availability of widget toolkits and similar GUI design applications allows re-use of common widgets such as, for example, buttons, check boxes, forms, slider controls, drop-down menus, tree views, toolbars, text boxes, table views, query boxes, pop-up help windows, status bars, etc. without a developer recreating each widget from scratch each time it is needed. When the data to be viewed and interacted with is well known and defined, the widget toolkits and drag-and-drop development environments can simplify many aspects of defining a GUI. However, even with a toolkit of available widgets, development of a GUI to potentially handle multiple, disparate types of data, or even data that may not be known at development time, often requires a level of programming proficiency and effort that offsets some of the benefits provided by availability of the toolkits.

Aspects of the present disclosure are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatuses (systems) and computer program products according to embodiments of the disclosure. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable instruction execution apparatus, create a mechanism for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.

These computer program instructions may also be stored in a computer readable medium that when executed can direct a computer, other programmable data processing apparatus, or other devices to function in a particular manner, such that the instructions when stored in the computer readable medium produce an article of manufacture including instructions which when executed, cause a computer to implement the function/act specified in the flowchart and/or block diagram block or blocks.

To aid in understanding aspects of the present disclosure, an example environment of Java-implemented portals and portlets is described, with respect to FIG. 1. However, one of ordinary skill will readily recognize that this environment is provided merely by way of example and the functionality and behavior described herein is not limited to this environment. The example environment is one particular example of a software application that provides a user interface to a user so that the user can view data and interact with that data.

Referring to FIG. 1, a server 102 can operate so as to provide a single web application or a plurality of web applications. In particular, the server 102 can provide a portal page that can include a number of different portlets. For example, a user can communicate with the server 102 using a user device 106 and a network 104, e.g., the Internet. The user device 106 can be a mobile device, a desktop computer, a laptop, or similar device that includes a user interface such as, for example, a browser 108. The browser 108 renders a portal page 110 that is received from the portal server 102. In particular, the portal page 110 can typically include a plurality of windows or portlets 112, 114 that compartmentalize different data. For example, portlet 1 112 may comprise weather-related information and portlet 2 114 may comprise a news feed. The portal server 102 consolidates this information from different data sources 116 and provides them as respective portlets 112, 114 within the portal page 110. When a user interacts with a portlet (e.g., makes a selection, clicks on a hyperlink, etc.), this interaction can be communicated back to the portal server 102 so that the content of the portal page 110 may be updated.

As mentioned above, the environment of FIG. 1 is merely an example environment of a more general case in which an application (e.g., portal server 102) provides a user interface (e.g., portal page 110) that has a component, or a plurality of components, (e.g., portlets 112, 114) with which a user interacts. The environment of FIG. 1 happens to be distributed over a network; however, the application and its user interface may both be implemented on a single machine as well.

While any of a variety of widgets can be used to construct a user interface, different “views” are a basic component of almost all user interfaces. For example, a table view is view in which a plurality of objects of a similar type are depicted in a list, often with multiple columns such as a table view 202 FIG. 2. Another view, a form view, may provide a detailed listing of every attribute of a particular object. Thus, a user interface can be developed which, in part, includes a composite view 200 that has a left panel with a table view 202 and a right panel with a form view 204.

An application developer may want to develop an application that includes the composite view 200. Thus, the composite view 200 can include the table view 202 which includes a table of entries 206 having a plurality of rows wherein each row is associated with a particular object (e.g., a computer system). The table view 202 is constructed so that a user can select a row (e.g., by selecting a hyperlink in one of the cells of the table 206). Based on a user's selection, the form view 204 will display detailed information about the computer system associated with the user's selected row.

The composite view 200 of FIG. 2 may be beneficial for a user interface that is implemented on a desktop computer or a device having a relatively large display screen. However, the application developer may want to utilize a different user interface for the table 202 and form 204 when a user's device is a mobile device or has a relatively small display screen. Thus, even though the information provided by a user interface can be the same in both instances, the application developer may want one user interface configuration for users using a desktop computer and a different user interface configuration for users using a mobile device.

In accordance with the principles and techniques described in this disclosure, a view registry 490 is implemented that identifies different views created by application developers and, for each such view, identifies attributes which help identify when that particular view may be better to use than other views in the view registry. In parts of the previous discussion and in the examples described below, the term “view” is used as one example of a user interface component. Thus, even though the term “view” may be used, other components of a user interface that are rendered for a user either to display data or to allow interaction with data are contemplated within the scope of the term “view”.

FIG. 3 depicts a flowchart of an exemplary method for creating a registry table in accordance with the principles of the present disclosure. An application developer may use a developer system 118 which is a computer platform that allows the application developer to create new views, locate existing views, modify existing views, and register new views with a view registry 490. A view registry 490 may be available through a web service or stored on local storage device. Using the view registry 490, an application developer can search for existing views that are similar to what they desire for their current application or to identify views that can be combined to form a composite view that they desire to construct. Also, widget toolkits and other user interface design tools may be available on the developer system 118 that provide basic building blocks that can be combined to define the configuration code of a composite view by an application developer who is designing a user interface portion for their application.

In step 302, of FIG. 3, an application developer who is designing a user interface either selects an existing view or begins with a new view. For example, a view “Example” may be a shell of a view that contains a table view and a form view. The table view is a known design element that is provided with a list of objects of the same type and displays them in a table such as the table 202 of FIG. 2. A form view is a known design element that is provided with an identifier for an object and displays a list of the attributes for that object such as the form view 204 of FIG. 2.

Using the basic view “Example”, the application developer modifies, or configures, the view, in step 304, to create a new version of “Example”. As an example, the application developer can configure the table view and the form view in a side-by-side configuration as shown in FIG. 2. When a user selects an item in row 206 of the table 202, the form 204 is populated with details about that selected item. This new configuration can be registered in the view registry as “Example_desktop”. One of ordinary skill will recognize that any appropriate naming convention may be used, but the name “Example_desktop” is useful in that it identifies that the basic view is “Example” and that this particular configuration is intended for “desktop” users.

The same application developer or another application developer, in step 304, can configure the “Example” view such that a table view is shown in a full screen by itself. When a user selects an item in the table, then the screen is replaced by a form view shown in the full screen. The form view includes a “BACK” button or some other design element to return to the table view. This configuration, or version, of the “Example” view can be registered in the view registry as “Example_mobile”.

Some languages read from right to left instead of left to right. Thus, an application developer may want to create yet another configuration of the Example view that places the table view on the right half of a window and the form view on the left half of the window. This configuration may be registered in the view registry as “Example_RtoL”.

The form view and table view can themselves be used to create different configurations to be registered with the view registry. Thus, the form view 204 can be a generic form view that can display any type of object having attributes. According to the form view, the attributes are displayed in a default order in a simple list. An application developer may, however, desire a custom form view when the object being displayed is of a particular type (e.g., objects of type A). The application developer can modify the generic form view such that the attribute fields for objects of type A appear in a particular order and in a particular arrangement (e.g., 3 columns of 3 elements each). The application developer could then register that form view as “form_ObjectA” in the view registry.

As part of configuring the new view that is to be registered, the application developer, in step 306, determines attributes associated with that new view that help identify user devices or user platforms that particularly benefit from the new view configuration. An example of some attributes that may be beneficial are provided in the table below:

View Attribute Usage viewName the exact name of the view e.g., com.dom.panther.Example_mobile alias a set of related views can be associated with one another by assigning all such views the same alias name e.g., Example create a Boolean value that indicates whether a view supports create operations dataClass identifies the class, if any, that the view belongs to e.g., list, form, table, etc. desktop a Boolean value that specifies whether a view supports desktop interaction locale an identification of language and country the view is intended for e.g., English - United States size identifies a supported display size e.g., 800×600 read a Boolean value that indicates whether a view supports read operations objectType identifies specific object types supported by the view touch a Boolean value that indicates whether the view supports touch interaction update a Boolean value that indicates whether a view supports update operations

Thus, in step 306, the application developer identifies one or more attributes that help differentiate one view configuration from another. Values are assigned to the identified attributes and the new view configuration is registered in step 308 into the view registry.

FIG. 4 depicts a conceptual example of a view registry in accordance with the principles of the present disclosure. The view registry 490 includes a respective entry 492, 496 for a plurality of different views. Each entry of a view (e.g., 492, 496) includes respective information 494, 498 about that view. The information for a view entry can include the name of that view (e.g., Example_mobile) and a location for the configuration of that view (e.g., com.dom.panther.example_mobile.js). This configuration is what the application developer created using a GUI development tool and is used to instantiate this view when it is encountered by a user executing the application. One of ordinary skill will recognize that the view configuration may be created using any of a variety of different tools and techniques available to an application developer for creating a view configuration. In the above examples, a view configuration “Example_desktop.js” could have been created that comprised a composite view 200 having a table view 202 on the left half of a screen, a form view 204 on the right half of the screen, and declarative code that tied the display of an object in the form view with a selection of a row in the table view.

A register entry (e.g., 492, 496) for a view may also include values for a plurality of attributes that help distinguish one view from another. Example attributes are identified in the table above but one of ordinary skill will recognize that other attributes may be added to that example list and all the listed attributes may not necessarily be used. As explained below, these attributes may be used at runtime to provide a user interface that is customized for the user's device or platform. Some of these attributes may also relate to the data (e.g., the object type) to be displayed. Thus, the user interface may be customized based on the runtime data being displayed.

FIG. 5 depicts a flowchart of an exemplary method for determining a user interface at runtime. The flowchart of FIG. 5 returns again to the example environment of FIG. 2 in which a portal server 102 is used to serve portlets 112, 114 to a browser 108. The steps in the flowchart of FIG. 5 may, however, be performed in any of a variety of different environments, other than just portlets, in which an application is executing that provides user interface elements to a user to allow that user to view data and interact with data.

Initially, in step 502, a request from a browser is received by a server requesting a portal page. The request from the browser can include information about the browser (e.g., an Operating System on which the browser is running, a processor of a user device which is running the browser, a character set used by the browser, a language and locale of the environment in which the browser is running, etc.). In response to the request for a portal page, the server constructs a portal page to send to the browser, in step 504. Each portlet included in the portal page will be comprised of its own portion of javascript that the browser will use to render the portlet in a window viewable by the user.

In step 506, the server may optionally determine which parts of the view registry 490 is relevant to the requested portal page. For example, if the request of step 502 indicates that a requesting device is a mobile device, then views in the view registry 490 related to requiring desktop interaction may not be relevant to the requested portal page and may not be sent. An example of portions of a view registry, for two registered views, that can be provided by a server is shown below:

{ “ViewName” : “Example_mobile”, “Alias” : “Example”, “ViewClass” : “custom”, “DataClass” : “custom”, “Locale” : “{‘*_*’:1}”, “Desktop” : false, “Touch” : true, “Config” : “example_mobile.js” } { “ViewName” : “Example_desktop”, “Alias” : “Example”, “ViewClass” : “custom”, “DataClass” : “custom”, “Locale” : “{‘*_*’:1}”, “Desktop” : true, “Touch” : false, “Config” : “example_desktop.js” }

In the above example, the first field provides a name for the view and the next fields provide a list of attributes and an associated value for the view. The last item in each view entry is a location where the actual configuration script, or code, for instantiating that view may be located so that it can be retrieved as needed.

In step 508, the server serves to the browser the portal page and the view registry, or at least a relevant portion of the view registry. The server may also include with the portal page a script, or similar executable statements, that can analyze the view registry, as explained below. Alternatively, the portal page may include javascript that, when executed, separately requests the view registry. In step 510, the browser receives the portal page, the view registry, and the javascript, for example, which can analyze the view registry.

In a portlet implemented using javascript, for example, the javascript may include a line referencing a function ViewRegistry that is executed, in step 512, to determine which view in the view registry is to be used to render the current portlet. The ViewRegistry function is included, as mentioned above, by the server as part of the portal page and is capable of analyzing the view registry. The syntax or format of the ViewRegistry function can vary greatly but, in concept, it specifies one or more criteria for the view that is to be used to render the portlet. For example, the ViewRegistry function can specify a value for alias, dataClass, etc. and identify those views in the view registry that best match the specified values considering attributes of the runtime environment.

In general, the executable line provided for a portlet can include an identifier that is related to one of the attributes of the views in the view registry. For example, the executable line provided for this portlet by the server for the ViewRegistry function can specify that alias=“Example”. The functionality of the ViewRegistry function can then search the view registry locating all the entries having a matching value (e.g., Example) for the attribute alias. The ViewRegistry function can also evaluate the other attributes such as desktop, touch, locale, etc. as compared to those same attributes of the system on which the portlet is to be rendered. Of the entries in the view registry, the function ViewRegistry identifies, in step 514, the view entry that provides a “best” match to the current user environment. The call of the ViewRegistry function can also specify alternative criteria such as, for example, ViewName=“Example_mobile” or DataClass=“list”. In the former example, this will result in identifying a particular view by name so that its configuration file is used for instantiating the view when rendering the portlet; and the latter example, will avoid looking a tables and forms when identifying a best view from the view registry.

One of ordinary skill will recognize that there are a variety of ways to identify a “best match”. For example, in the above example of the portion of the view registry, there is an attribute “Locale: {*_(—)*:1}”. This example syntax may be interpreted that any language and location (e.g., the wildcard *_*) will match this view entry but that it will be given a weight, or value, of “1”. An alternative view entry in the registry might have the same exact syntax for all the other attributes except for “Locale: {EN_US:5}”. In this instance, if the user local is identified as the English language in the United States, then this match has a weight, or value, of “5”. Thus, the ViewRegistry function can determine a best matching view by assigning a “1” to each attribute that matches and a “0” to all not matching attributes. A sum can be tallied for each view entry in the view registry and used to rank the view entries to determine the “best match”. Also, assigning weighted values to one or more attributes may be used when generating a score.

Once the ViewRegistry function has identified the best matching view from the view registry, the location of the configuration information is retrieved from the registry entry, in step 516. The location may point to code that has already been loaded as part of the current portal page, code that may be present in a browser cache because it was referenced earlier, or code that is resident on the portal server or other system. If the view is a re-configuration of a previous view, configuration information that re-configures previous view into a new view is loaded. If the view is a wholly new view, then the code that implements that view can be loaded. The retrieved view configuration code can itself include references to ViewRegistry to be resolved for selecting additional views from the view registry. In other words, the configuration for a view may include sub-views and these sub-views may be loaded and parsed for any sub-views that they may contain. Thus, in step 518, the executable code that was provided by the server for analyzing the view registry recursively parses through the JavaScript, for example, for rendering a portlet to select the various, potentially nested views and sub-views to use to render the portlet. Thus, the loop between steps 512 and 518 in FIG. 5 may be repeated until all the code for rendering the portlet has been determined. Once all the code for rendering a portlet in a user interface has been identified and retrieved, views using retrieved code can be instantiated to render the portlet.

Because a view entry in the view registry can point to a location on the portal server, or other system, where the configuration code for implementing that view resides, the views which are used to provide the user interface can be easily updated and used even while a user is accessing the portal page. Also, new views can be added to a view registry to take advantage of new devices or different capabilities as they are developed without requiring any change to the portal server.

Referring to FIG. 6, a block diagram of a data processing system is depicted in accordance with the present disclosure. A data processing system 400, such as may be utilized to implement the hardware platform 108 or aspects thereof, e.g., as set out in greater detail in FIG. 1-FIG. 5, may comprise a symmetric multiprocessor (SMP) system or other configuration including a plurality of processors 402 connected to system bus 404. Alternatively, a single processor 402 may be employed. Also connected to system bus 404 is memory controller/cache 406, which provides an interface to local memory 408. An I/O bridge 410 is connected to the system bus 404 and provides an interface to an I/O bus 412.
